Answer:

Oxides, and water (and water is an oxide of hydrogen).

Explanation:

Typically we combust hydrocarbons; certainly, we do so in order to make our goggomobiles go.

If we represent petrol or diesel as hexanes:

#C_6H_14(l) + 19/2O_2(g) rarr 6CO_2(g) + 7H_2O(l)#

Of course combustion is never complete in an internal combustion engine; some products of incomplete combustion result, i.e. #CO# and particulate #C#.

#C_6H_14(l) + 8O_2(g) rarr 4CO_2(g) + C(s) + CO(g) + 7H_2O(l)#

Are mass and charge conserved in these reactions? If not, they should be!
